/*
 * form-contrast.css — TRUE Platform Form Contrast Override
 * Deployment: /public/form-contrast.css → index.html <link>
 * Architecture: isolated override layer, zero JSX touch, hot-removable
 * Rationale: form contrast = data quality issue, not cosmetic
 *   poor contrast → skipped fields → incomplete captures
 *   → lower scores → worse ledger density
 * OBS-UX-001 compliant
